It seems like a neat idea. If it can just be layered on top of Jax pretty easily… I dunno, seems so simple it might actually get traction?

I wish I could peek at the alternative universe where Numpy just didn’t include broadcasting. Broadcasting is a sort of ridiculous idea. Trying to multiply a NxM matrix by a 1x1 matrix… should return an error, not perform some other operation totally unrelated to matrix multiplication!

Broadcasting is an excellent idea. Implementations do have warts, but e.g. pytorch would be really painful without it.

Broadcasting is a sort of generalization of the idea of scalar-matrix product. You could make that less "ridiculous" by requiring a Hadamard product with a constant value matrix instead.

Scalar-matrix multiplication doesn’t seem that weird; automatically converting a 1x1 matrix to a scalar is the weird seeming thing, IMO.
